These 10 plants don’t just make your garden gorgeous — they’re also surprisingly easy to grow.

Butterfly Bush (Buddleia Lo and Behold® ‘Blue Chip’) Zones 5–9

Buddleias are easy-care plants, but they’re invasive in some areas. Look for sterile cultivars ‘Blue Chip’ (shown) and ‘Purple Haze,’ which don’t set seed and therefore don’t run wild. “They’re shorter and more compact, and because they’re sterile they have a much longer flowering season,” Staddon says. “Get them going in the garden and they’ll quietly take care of themselves.”
